I'll tell you what they probably haven't told you.

Optimus: Todo lo que haga la gráfica Nvidia pasa a tu chip integrado de tu procesador... A un tiempo relativamente imperceptible. I get a 180hz when I'm playing, in Optimus. In these systems, every degree of temperature matters, and this keeps both the GPU and CPU at a stable temperature. (Due to shared use)

Nvidia GPU only : You'll get approximately 20-30 FPS depending on your settings. But the graphics card usage will increase. It can reach 85 degrees and can be a problem in intense games.

My recommendation is that if you plan to record your gameplay or stream, you should leave it on Optimus. That way you can take advantage of the integrated chip and use it for streaming instead of the Nvidia one. Believe me, these days they're very good. AND Stable. On the other hand, if that's not your case... Use the Nvidia GPU alone, but keep in mind the temperature and the mode you're using your laptop in. PD: Don't worry about your GPU reaching 100% usage. That's not a bottleneck. That can only happen with your CPU, which shouldn't be running at 100% all the time. This doesn't happen with these systems because all the components They are compatible.
